ARTIFICIAL DENTUBE.

Application filed January My invention relates to the art of artificial denture and pertains more particularly to a new article of manufacture in the form of sheet metal palates for upper plates. One object is to provide an article of this char acter which can be stamped out in different sizes and supplied to the trade at less cost than cast metal palates can be produced by individual members of the dental profession under the practice now in common vogue, which requires more or less special equipment and skill on the part of each member undertaking the production of said cast metal palates to meet the demands of his practice. The sheet metal palate has further important advantages over the cast metal palate in the way of lesser weight and porosity, and in the ease and accuracy wlth which it may be shaped over the model of the patients palate.

A further ob 'ect of the invention is to form the sheet metal palate in such manner that a firm and sanitary union may be efi'ected with the vulcanite in which the artificial teeth are embedded.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is an inverted plan view of an artificial plate provided with a palate constituting the important feature of the invention.

Fig. 2 is a transverse section on line IIII of Fig. 1.

Fig. 3 is an inverted detail plan view of the palate.

Fig. 4 is an enlarged fragmentary section of one corner of the palate.

Referring now in detail to the various parts, A designates the complete plate which consists of the sheet metal palate 2, the vulcanite B, and the artificial teeth C. The vulcanite B and the teeth C are of usual construction, but the palate 2 is stamped from any suitable sheet metal and provided with novel means for firmly holding it in position in the vulcanite B.

As shown more clearly by Figs. 2 to 4, inclusive, the palate 2 is provided at its upper side with shoulders 4 and 6 which are parallel to each other and the entire margin of the palate 2, excepting the rear 13, 1925. Serial No. 2,172.

margin 8. The shoulders 4 and 6 are spaced apart to leave an intervening groove 10, for the reception of a portion of the vulcanite B.

12 designates an abutment on the under side of the palate 2 and parallel to the margin thereof from which said abutment 12 is spaced a short distance. A row of holes 16 are formed in the palate 2 and extend from the shoulder 4 to the abutment 12, while another row of holes 18 are formed between the margin of the palate and the abutment 12, to receive a portion of the vulcanite B. Ribs 19 are formed on the palate 2 between its margin and the abutment 12 to reinforce said palate 2 and hold the same more firmly in the vulcanite B.

In practice the proper size palate plate 2 is selected and burnished or otherwise fitted to the plaster cast or other model, not shown. Prior to the operation of fitting the palate 2, the margin of the model is built up with wax or other suitable compound to prevent the margin of said palate 2 from being pressed downwardly and thereby disfiguring or eliminating the shoulder 4 and the abutment 12. If a relief is desired the model is built up to form the same in the palate 2 as the latter is being swedged or burnished over said model.

After the palate 2 has been properly fitted B, forming sanitary joints and lending a neat and attractive appearance to the completed plate A.

From the foregoing description taken in connection with the drawing, it is apparent that I have provided a palate embodying the advantages above pointed out, and while I have shown two forms of said palate, I reserve the right to such other forms as properly fall within the spirit and scope of the invention as claimed.

side of the palate from that containing said shoulders and parallel with the front and side portions of the margin of said palate, 10 and ribs adjacent to said abutment.

In testimony whereof I aflix my signature LESLIE EATON.
